pls send me answer of this question all the parts pls and i will rate you sure, pls solve a,b,c and d and also a and b A 200-kg dragster (racing car) exerts a constant force of 4000 N during a race. The coefficient of kinetic friction between the tires and the pavement is .15. If the drag strip is 1000 m long, determine:a. The net force on the dragster. b. The acceleration of the dragster. c. The time it takes for the dragster to finish the race.d. The dragster's velocity at the end of the race.The dragster now needs to slow down, so it opens a parachute. The force of air drag is 3500 N. The driver also locks the brakes of the dragster, and the coefficient of kinetic friction becomes .75. Determine:a. How long it will take to stop the dragster.b. The distance the dragster travels while stopping.

Top GunContext Watching the excellent movie Top Gun: Maverick , you are impressed by the cables used to stop the fighter planes on the aircraft carrier. You would like to model the tension in the cable needed to stop the plane, so that you can choose a type of cable that can withstand this tension. Constraints The mass of the fighter plane and its initial speed are known.The length of the airstrip is known.The force exerted by the cable is assumed to be constant. It is assumed that a single cable stops the aircraft by exerting a horizontal force perfectly opposed to the movement of the aircraft. Modelization Model the modulus of force exerted by a cable that succeeds in stopping a fighter plane, given known parameters. Then test your model with the following parameters, giving your answer in kN. Aircraft mass = 25000 kg Initial velocity = 245 km/h Track length = 80 m
The motor exerts a constant force of T (N) on the cable. The final speed of the crate of mass m (kg) is v (m/s).

Engineers are designing a system by which a falling mass m imparts kinetic energy to a rotating uniform drum to which it is attached by thin, very light wire wrapped around the rim of the drum (Figure 1). There is no appreciable friction in the axle of the drum, and everything starts from rest. This system is being tested on earth, but it is to be used on Mars, where the acceleration due to gravity is 3.71 m/s?. In the earth tests, when m is set to 15.0 kg and allowed to fall through 3.00 m, it gives 350.0 J of kinetic energy to the drum.
